Pilot-scale Study on Enhanced Coagulation Treatment of the Micro-polluted Reservoir Water

According to the characteristics of raw water of the micro-polluted reservoir, jar-test and pilot scale experiments were employed respectively for water treatment. The results showed that the particles with large size decreased when ozone pre-oxidation was applied, meanwhile, the organic matters with unsaturated chemical bonds decreased obviously. Moreover, the treatment efficiency of HPAC was better than which of traditional PAC or aluminum sulfate. The results also showed that turbidity, organic matters and coliform could be treated efficiently by ozone pre-oxidation combined with traditional technologies.
